Metered-Dose Inhaler with AeroChamber and a Mask

A metered-dose inhaler (MDI) is a piece of equipment that enables your child to breathe or inhale a fixed dose of his / her medication.

When your child uses a metered-dose inhaler, the medication works quickly as it goes directly to his / her lungs. A spacer is always used with an MDI to maximize the amount of medication inhaled.

  1. AeroChamber and a MaskThis type of spacer is for the child who is too young to always be able to breathe in through his / her mouth at the right time. Usually this is someone 6 years of age or under or who is unable to use a mouthpiece.
  2. Check the expiration date on the device before using it. Discard it if it has expired, and get a new prescription.
  3. Remove the plastic protective cap from the MDI.
  4. Insert the MDI of medicine into the plastic holder on the rubber end of the AeroChamber.
  5. Shake the AeroChamber and the MDI.
  6. Sit your child on your lap. The back of your child's head should be against your chest.
  7. Apply the mask to your child's face so that the nose and mouth are covered.
  8. Spray 1 puff from the metered-dose inhaler into the AeroChamber.
  9. Keep the mask in place for 6 - 8 breaths. Have your child breathe through his / her mouth, if possible. You can have your child imitate you as you deep breathe through your mouth. Watch the child's chest to count breaths.
  10. Rest, wait 1 minute and repeat according to the doctor's direction.
  11. At least once a week, remove the back piece of the AeroChamber only. Soak the back piece and chamber for 15 minutes in lukewarm water and liquid detergent. Rinse in clean water and allow it to air dry in an upright position.  

Some metered-dose inhalers will still appear to be working even after the medication is gone, which can be dangerous.

  • If your child uses his / her inhaler only as needed, you can determine the amount of medication inside by removing the canister from the plastic sleeve and shaking it gently with your index finger on the flat end. Obtain a refill when a small amount is remaining.
  • If your child uses his / her inhaler at least once a day, you will need to get a refill from the pharmacy about once a month.
